Timelines describe the events that occurred before another event, leading up to it, causing it, and also those that occurred right afterward that were attributable to it. Timelines are often bulleted lists or tables. Timelines in paragraph format (proselines) are not recommended.

WikiProject Timeline Tracer is making an effort, as of January 2008, to seek out and standardize timeline and chronological references.

See also the Featured list criteria and Wikipedia:Lists as style guides, and relevant Featured lists such as Timeline of chemistry, Timeline of the Manhattan Project, and List of sieges of Gibraltar as examples.
